Regenerative harmonics filter IP55 (400V/50 Hz)
CNW 957 LCL filters are used especially in regenerative converters (AFE), but also for inverters for renewable energies. The main purpose of this filter is to eliminate the PWM frequencies for protect the supply network. Nominal Voltage: 400 V Rated current: 14 – 74 A
THREE-PHASE SINE FILTER IP55
CNW 933 Sinusoidal output current – save costs and trouble-free operation. For particularly long cable lengths of > 100m between inverter and motor the shielded cable for EMI suppression used can cause a capacitive coupling. A conventional motor choke can not provide sufficient damping in such cases.

REOHM Series 155 – combination
As soon as an electric machine works as a generator (electric motor brake), the braking resistor protects the machine from an excessive voltage increase in the intermediate circuit. REO braking resistors achieve better heat dissipation and better impulse loading by filling heat transport media in the vicinity of the wound body.

Single-phase line reactor 4% Uk
CNW 901 Reduce grid disruptions – save up to 20% on energy costs. A line reactor relieves the supply network by compensating for the harmonic reactive power. The harmonic harmonics and commutation notches are greatly reduced. The converter electronics and the intermediate circuit capacitors are protected by using a line choke. Starting currents and current peaks are reduced […]
